Terex® Minerals Processing Systems (Terex MPS) has expanded their CR Series portable plant line with the addition of the Terex® Cedarapids CRS620S screen plant (Fig.). The plant features the next generation, patent pending LJ-TSV screen. The new screen increases production and handles applications not possible with traditional horizontal screens because it combines the legendary El-Jay™ high g-force oval stroke motion with adjustable slope operation. This plant can handle larger deck loads and larger screen openings. Hydraulics quickly change the screen slope in 2.5° increments up to a maximum of 7.5° to best fit the application. Screen openings up to 6” (152 mm) are possible.
Patent pending “slant spring” screen suspension provides stability at all slopes. The plant utilizes large capacity conveyors to handle the high production capabilities of the new LJ-TSV screen. The 48” (1219 mm) wide fines conveyor with its elevated discharge and the two 30” (762 mm) wide reversible cross conveyors which extend up to 42” (1067 mm) beyond the main frame, easily feed off-plant conveyors. Roll-away blending chutes and extended walkways allow easy access to screen cloth. The patented low-maintenance flex shaft screen drive eliminates drive belt influence on the screen motion, belt whip, belt slippage, and spring loaded belt tensioners. There are no drive adjustments necessary when the screen slope is altered. In addition, the new flex shaft drive folds for travel to minimize plant transport width.
